该函数提供了一个ARMA谱估计，最大熵满足相关约束（极点数）和倒谱。 该函数需要3个输入：输入信号、分母阶数、分母阶数和输出变量分别为：分子系数、分母系数和输入噪声功率的平方根。(The function requires 3 inputs: Input signal, Order of denonominator, Order of Numerator and the output variable are: numerator coeffients, denominator coeficients and square-root of input noise power.)

a smaple matlab program

it is single phase cycloconverter used in many ways to control the frequency or rather would say reduce the frequency to control the speed of motor but here iam using only resistive load because my teacher only give me this project. To use simulink please change the solver type to ode23tb

基本的拉格朗日乘子法(又称为拉格朗日乘数法)，就是求函数f(x1,x2,...)在g(x1,x2,...)=0的约束条件下的极值的方法。其主要思想是引入一个新的参数λ（即拉格朗日乘子），将约束条件函数与原函数联系到一起，使能配成与变量数量相等的等式方程，从而求出得到原函数极值的各个变量的解。 (Basic Lagrange multipliers (also known as Lagrange multiplier method), is of a function f (x1, x2 ,...) in g (x1, x2 ,...)= 0 constraints under the conditions of extreme value methods. The main idea is to introduce a new parameter λ (the Lagrange multiplier), the constraint function is linked together with the original function, so variables can be paired with an equal number of equations equation, thus obtained by the original function extreme solution of the various variables.)

说明：  SINS仿真Matlab程序，对初学者还算全，应该有点用处，虽然比较简单，也省些前期编写的麻烦， 希望能花更多时间研究些专门的有用处的东西。如大家有需要还可增加一些其它内容(SINS Matlab simulation program, for beginners fairly full, should be of some use, although relatively simple, but also save the trouble of some pre-prepared, I hope to spend more time to study some specific useful things. If you need to also increase the number of other elements)
